Add WMI interface(WMI_VDEV_SET_TWT_EDCA_PARAMS_CMDID) to
configure EDCA/PIFS param for LL SAP.
This configuration depends on edca_param_type.
If edca_param_type is 0 then host will configure EDCA param and
send it to firmware via WMI interface.
If edca_param_type is 1 then host will configure PIFS param and
send it to firmware via WMI interface.
